HANSON ROBINSON, OF SOUTH BEND, INDIANA.

FLUSHING-NOZZLE.

all whom 'it 'may concern:

Be it known that I, I-IANsoN ROBINSON, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Flushing- Nozzles, of which the following is a specication.

This invention relates to improvements in flushing nozzles of the type used on flushing wagons which are mainly employed for washing city pavements, and has for its particular object to provide a 'device of this character that will discharge a flat broad stream at an angle to the pavement and means for causing said stream to contact with the pavement with equal force throughout its flushing area.

A further object is to provide a nozzle `formed of separate sections, whereby its interior can be polished to make its discharge more ei'fective.

"With the above and other objects in view, the present invention consists in the combination and arrangement of the parts as will be hereinafter more fully described, shown in the accompanying drawing, and pointed out in the appended claims, it being understood thatchanges in the form, proportion, size and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing Figure l is a perspective view of my improved device. Fig. 2 is a front elevation thereof, and Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2.

Like numerals of reference designate corresponding parts in all of the figures of the drawing.

Nozzles of this character are especially applicable to flushing wagons provided with a water tank and a tank of compressed air, by means of which the water is discharged with greater or less force, and they are designed t0 project a diverging stream against the pavement at an inclination to wash the debris toward the gutters, but in nozzles of this character heretofore used, the force of the stream at the point of its greatest throw is usually somewhat less than its nearest throw. This is caused by the resist-ance of the air which tends to break the flat stream into a spray, and as the flushing value of the nozzle depends upon keeping the stream Specification of Letters Patent.

solid until it strikes the surface of the street, i

it caused the present improvement to be devised.

Referring to the drawing, t and 5 designate the two sections of the improved nozzle, each of which is provided with inclined and rounded walls having diverging sides with iianges 6, which when brought into register with each other, form a tapering chamber 7 which gradually merges into a flat wide mouth 1l in a front wall 8 formed by relatively thick flanges on the widest part of each section. The sections are also formed with semi-cylindrical extensions 9 at their inner ends so that when brought together a cylindrical neck or nipple is formed by which the nozzle is secured to the discharge pipe 10 of the flushing cart or wagon in any well known manner. The front walls of the sections are recessed on their dividing lines to form a wide narrow discharge opening 11, and said recesses are gradually deepened toward one side to form said discharge opening of gradually -increasing depth from one side to the other. rlhus when the device is in operation a flattened stream of water of increasing volume in cross section is discharged therefrom, which preserves its solidity throughout its flushing area. In other words, the water strikes the pavement with equal force for the entire width of the stream. The sections are secured together preferably with screws 12, and it will be understood that if desired suitable packing may be inserted between the sections to prevent leaking. Previous to securing the sections together the walls of the chamber 7 are highly polished, which renders the delivery of the water more effective. Thus the advantage vof forming the nozzle in sections can be clearly seen.

Nozzles of this type are usually positioned to discharge the stream from a point near the wagon to a distance from the wagon, and by forming the discharge mouth of gradually increasing width from one side to the other, the widest portion of the mouth being adapted to throw the water the greatest distance, the volume of water discharged will retain its solidity or force throughout.

Having thus described the invention, what is claimed is 1. A iushing nozzle formed in sections, each of which comprises a rounded and inclined wall having diverging sides and terminating at its forward end in a thickened fizinge which is provided with a recess on one of its feces, said recess increasing in depth from one side to the other, and side flanges provided with apertures, whereby said sections can be secured together to form a tapering chamber merging into :L flat wide month of increasing dept-h froin'one side to the other.

Q. A flushing nozzle formed in sections,
